Document Summary
Find the point(s), if any, on the x-axis between 0 and l for which the total electric field is zero. Problem #2: use ampere"s law to calculate the magnitude and direction of the magnetic field due to an infinitely long wire as a function of the distance r from the wire. Assume that the wire is perpendicular to this page and carries a current i into the page. Express the direction of the magnetic field as clockwise or. Counterclockwise : two long, parallel wires perpendicular to this page are located as shown in the figure. Wire 1, carries a current i into the page, while wire 2 carries a current i out of the page. Use the result from part a) to find the magnetic field (magnitude and direction) for every point along the positive x-axis as a function of the coordinate.
